WHEAT-DRILL.

SPECIFICATION forming part of Letters Patent No. 445,076, dated January 20, 1891.

Application filed July 5,1890. Serial No. 357,894. (No model.)

ed certain new and useful Improvements in \Vheat-Drills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in wheat-drills; and it consists in the novel construction and arrangements of the different parts hereinafter fully set forth and described.

In the drawings, which illustrate the manner of carrying out my invention, Figure 1 is a side elevation of my device. Fig. 2 is a top plan view showing the cover of the hopper A partly broken away. Fig. 3 is a central longitudinal section, showing the manner in which the spouts K are secured to hopper A. Fig. 4 is a rear view of my device. Fig. 5 is a detail in perspective of the jointed spout which conveys the grain from the hopper A to drill-plows ll. Fig. 6 is a detail view of the plow 11 secured to the spout G. Fig. 7 is a broken-off detail view of the hopper-support 13. Fig. 8 is a detail in perspective of the deflector.

Referring to the drawings by letter, A. represents a hopper made a suflicient length to distribute wheat to all the spouts K, being mounted on supports 13, which. are properly secured on frame-work l).

C is an axle, on which are mounted wheels X for carrying said wheat-drill. E is a suitable tongue by which the wheat-drill is drawn. F are inclined beams or timbers to which the boots G are pivotally bolted, said boots G be ing provided with a suitable plow H, which cuts the furrow for the reception of the wheat through the dirt upon either side between the spouts in such a manner as to form a ridge, thus leaving wheat in the furrow between each row. These ridges serve to protect the wheat from the wind during the winter, and in the spring the ground may be leveled by using a harrow or any suitable implement for that purpose.

g is a deflector secured on the under side of boot G immediatelyin the rear of the plow II in such a position that the wheat passing through boot G falls on deflector g, and is thereby scattered over an area of aboutfour inches.

0 is a shaft running parallel with the main axle O and provided with flanged metallic wheels 0. These wheels 0 are provided with perforations c, in which the wheat or grain to be sown collects when falling through the hopper A, and as said wheels revolve the grain is dropped into the conducting spout or trough K.

I is a metallic brace rigidly bolted to the inclined beams or timbers F and pivotallyab tached to the boot G near its top.

J is a segmental iron brace bolted to inclined beam F, and then secured to boot G by wooden pin j. The object of this wooden pin is to provide a brace which will Oder as little resistance as possible in case plow H should come in contact with any obstruction, in which case the wooden pin would break, allowing said plow H and drill-spout G to swing backward.

K are the spouts which conduct the grain from hopper A to boots G, these being made in sections hinged together in the manner illustrated in Figs. 3 and 5, thus allowing them to be moved with little difficulty when they are to be raised from the ground.

Sections 7a and 70 are secured and held in position by bolts 7t and metallic brace 70'.

L is a cross-beam which connects the framework D, the same being secured and held thereon by suitable angle-braces Z.

Z is a suitable handle, bolted or otherwise rigidly secured on beam L, by which all the drills may be raised out of the ground.

M are chains which pass through eyes m in beam L, said chain M being provided with a ring or loop which constitutes a handle for operating them singly; or when only one drill is to be raised from the ground this is done by a man who walks behind the drill.

N is a segmental rod or iron brace properly secured to shaft 0 and pivotallysecured to frame D. This passes through a perforation in the lever O, which, operating backward or forward, throws gear-wheels P out of gear with the central gear-wheel S.

T is a gear-wheel keyed or otherwise rigidly secured on main axle C. This meshes with gear-wheel S, which in turn meshes with are slightly inclined, so as to conduct the grain to the flanged wheels 6. Thesezstrips U are provided With a slide or valve, which allows the grain to pass through the hopper in the desired quantity. The slide or: Valve may be operated to allow a suitable quantity of grain to pass through said hoppers U onto wheels 0.

b is a recess in the support B, in which operates the journal b, which carries the revolving shaft. 1') are the legs of said supportB, which rests on the horizontal beams D.

f is a king-bolt, which passes laterally through cross-beam L to which is bolted theiron braces f by suitable bolts, said braces f being then properly secured to inclined beams F.

L is a cross beam connecting parallel beams D D and forming a bearing for tongue E.

Having my device constructed in this manner it will be found a very easy matter to opcrate it.

The plows H, throwing the soil up in ridges between the rows of Wheat, serve to protect it from the winter Winds after it has come up.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is- 9 in a Wheat-drill, the combination of a main frame, a hopper mounted thereon, devices for distributing the grain, and a trough connecting said hopper and distributing devices,

said trough being composed of a series of concave sections, each of said sections being loosely pivoted at its corners only to the section next adjoining, whereby said trough is adapted to conform to any desired curvature, and transverse braces connected to the corners of said sections at the point of pivoting, as described. 7

In testimony whereof I afiix my signature in presence of two witnesses.
